AA & Ball Of Powder

I decided to cut open a new aa x-lite target load to weight the components,shot was number 8 and around 6 pellets over what 1 oz by weight should weigh but is the powder correct in these shells , and what i mean is a rolled ball form/clump correct??? powder did weigh 16.5 grains

I load solo 1000 powder and have had to dismantle a shell a time or two. never had any that "clumped". seems to me that it would take alot of wad pressure and a long period of time for powder to form that way unless it was damp. I am no expert on these matters but it sure looks like winchester/olin would look into this a little further. could be the cause of some of the barrels being destroyed buy their shells. Nipper if you do not feel safe shooting these then send them to me I will have them properly disposed of!
